7.While watching the signal strength number to ensure that it stays at maximum, tighten the elevation nuts in the following sequence:

a.Snug the left nut but do not completely tighten it.

b.Snug the right nut but do not completely tighten it.

c.Fully tighten the left nut (torque to 12 ft-lbf).

d.Fully tighten the right nut (torque to 12 ft-lbf).

Adjusting polarization Polarization refers to rotation of the antenna (as shown in Figure 44) and is measured in degrees from zero (no rotation), positive or negative. Polarization is positive east of the satellite longitude and negative west of the satellite longitude.

Figure 44 illustrates how you adjust the antenna’s polarization by rotating the antenna.

Figure 44: Adjusting elevation

To adjust polarization, follow these steps:

1.Fine-tune the polarization setting by loosening the polarization nuts just enough to enable you to rotate the antenna reflector a few degrees in each direction. If the signal strength does not change, set the polarization to the value calculated by the installation software. Otherwise, set the polarization at the setting where you peaked the signal.

2.While monitoring the signal strength number to ensure that it stays at maximum, tighten the polarization nuts.
